A material useful as a fuel heavier than gasoline or as a blending component for a distillate fuel comprises a fraction boiling in the range of from 121.1 to 371.1 deg C derived from a Fischer-Tropsch process, and contains at least 95 wt% paraffins with an iso to normal ratio of from 0.3 to 3.0, no more than 50 ppmw each of sulfur or nitrogen, less than 0.5 wt% unsaturates, and at least 0.001 wt% oxygen (water-free basis). The oxygen may be present as mono-oxygenates. The mono-oxygenates are preferably primarily in the form of linear alcohols, more preferably C12 to C24 primary alcohols. The material exhibits good lubricity in the standard Ball on Cylinder Lubricity Evaluation (BOCLE) test despite being free of added lubricity-imparting additives.
